Nium

Nium is doing something that sounds honestly useful rather than gimmicky: letting businesses fund Visa and Mastercard cards directly with stablecoins while handling the crypto-to-fiat conversion behind the scenes through a single API. Most crypto-to-fiat play usually involves forcing users through exchanges or complicated DeFi routes, so the idea of just loading a card with USDC or USDT and having it just work is the kind of practical bridge between crypto and real-world spending that actually makes sense for companies sitting on stablecoin treasuries. I don't have real traction numbers or customer examples to know if it's gaining real adoption, but the mechanism itself is sound enough that I'd watch for signal on this one.
